编前话:高空抛物现象曾被称为“悬在城市上空的痛”。在上海“陋习排行榜”中,它与“乱扔垃圾”齐名,排名第二。高空抛物,是极不文明的行为,而且会给社会带来很大的危害。有数据显示:一个30克的蛋从4楼抛下来会让人头上肿包;从8楼抛下来可以让人头皮破损;从18楼甩下来可以砸破行人的头骨;从25楼抛下可使人当场死亡。因为物体的相对位置越高,其下落速度越快,下落后造成的伤害也越大。将空啤酒瓶分别从18楼和25楼的高度抛下,均可造成致命伤害。一枚4厘米的铁钉从18楼甩下时,可能会插入行人的脑中。
The first words: the phenomenon of high-altitude parabolic was once known as “the pain hanging over the city.” In Shanghai “bad habits list ”, it “litter ” par, ranked second. Parabolic altitude, is very uncivilized behavior, but also to the community a great harm. Statistics show that a 30-gram egg thrown off the 4th floor will make the head swollen; the thrown-down scalp will be damaged from the 8th floor; the pedestrian skull will be smashed down from the 18th floor; People died on the spot. Because of the relative position of the object is higher, the faster the drop, the greater the damage caused by the drop. Dropping empty beer bottles from the 18th and 25th floors, respectively, can cause fatal injuries. A 4-cm iron nailed down from the 18th floor may be inserted into the pedestrian’s brain.
